Here's my site: http://hyperreal.us/
You will notice that images embedded in my posts look fine. They also look fine in the image slider on the home page, but when they show up as featured images in the posts or as links in "recent articles", the images are really pixelated.
Do I need to resize the featured image or mess with the CSS to change the resolution for featured images? Is this because I changed the width of my posts and of my featured images? Maybe I neglected to also change some critical bit of code that would also update the resolution? Any ideas?
